What is AI? Artificial Intelligence (AI) is the simulation of human intelligence by machines, especially computer systems. AI enables machines to perform tasks that typically require human intelligence, such as understanding language, recognizing patterns, solving problems, and making decisions. Key Concepts of AI: Machine Learning (ML): A subset of AI where computers learn from data… Read More »

Java is a multi-threaded programming language which means we can develop multi-threaded program using Java. A multi-threaded program contains two or more parts that can run concurrently and each part can handle a different task at the same time making optimal use of the available resources specially when your computer has multiple CPUs.

The term network programming refers to writing programs that execute across multiple devices (computers), in which the devices are all connected to each other using a network. The java.net package of the J2SE APIs contains a collection of classes and interfaces that provide the low-level communication details, allowing you to write programs that focus on solving the… Read More »
Java provides a mechanism, called object serialization where an object can be represented as a sequence of bytes that includes the object’s data as well as information about the object’s type and the types of data stored in the object.

Although these classes were quite useful, they lacked a central, unifying theme. Thus, the way that you used Vector was different from the way that you used Properties. The collections framework was designed to meet several… Read More »
